Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed April 11, 1913. Serial No. 760,427.

To all whom it may concern:

Be it known that I, PATRICK F. RYAN, oi

ticularly to the means for holding the blades.

in shearing contact and for limiting their open movement.

The main object is to produce a more effective guide and limiting stop for holdingthe cutting edges of the blades in shearing contact throughout their entire lengths as the same are closed and at the same time serving the additional purpose of limiting the opening movement of said blades without increasing the number of parts, thereby permitting the entire shears to be manufactured at a much lower cost than would be possible if the guides and stops were made of separate pieces or more intricate in their formation.

Other objects and uses will be brought out in the following description.

In the drawingsFigure 1 is a top plan of grass shears embodying the features of my invention. Fig. 2 is a transverse sectional view of the same shears taken on line 2-2, Fig. 1, showing the ends of the blades and guide stops. Fig. 8 is a detail sectional view taken on line 33, Fig. 1. Figs. 4: and 5 are perspective views of the rear ends of the shearing sides of the blades showing the guides and limiting stops.

In order that my invention may be clearly understood, I have shown a pair of shearing blades 1- of sheet steel as mounted upon the ends of a U-shape spring handle 2 and provided with cutting edges 3-, the heels or rear ends of the cutting edges lapping one upon the other while the rear ends of the blades are preferably straight and disposed in substantially the same transverse plane and are provided with integral tongues anear their cutting edges. These tongues are stamped from the same piece of metal as their respective blades while the latter are being formed in the blanks and project rearwardly from the rear edges thereof, but are subsequently returned to form guide slots 5 and blade-retaining lips -6-, the tongue of each blade being returned forwardly across the rear edge and outer face of the other blade so that the return bends of both tongues lie in the path of movement of each other to limit the opening movement of the blades. In other words, the tongues are formed integral with the overlapping portions of the rear ends of the blades and are arranged so that the tongue of each blade laps upon the adjacent portion of the other blade some distance from its shearing edge so that when the blades are opened by the action of the spring 2, the return bends of the tongues will abut one against the other to limit such opening movement, it being understood that the spring is tensioned as shown to open the blades. By extending the tongues forwardly or lengthwise of and upon the outer surfaces of the blades near their cutting edges, it is evident that said cutting edges will be held into close shearing operation and will also serve to limit the opening movement of the blades, thereby assuring a close travel of the cutting edges from their bases to the points without adding any extra parts to the shears, which enables said shears to be manufactured at an extremely low cost without sacrificing the quality of the style or efficiency of the entire shears.

What I claim is:

1. A grass shears comprising a spring handle and a pair of blades secured thereto and having their rear ends provided with integral tongues, the tongue of each blade being bent around the heel and upon the outer surface of the other blade in sliding engagement therewith.

'2. A grass shears comprising a pair of shearing blades having the rear 'ends of their cutting edges lapping one upon the other and the rear ends of the overlapping por-,
